An Informal ACA is normally NOT depicted on charts and maps.

• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (A)

Airspace coordination areas are used to manage and deconflict airspace when coordinating aircraft with ground fires. Only officially published and authorized areas appear on standard maps and charts. An informal ACA is a temporary, ad hoc boundary created for a specific operation and does not have official chart notation. Because it isn’t part of the published airspace plan, it’s normally not depicted on charts or maps. You’d handle an informal ACA through direct coordination with airspace control and via your operation orders or briefings, not by relying on chart symbols. So the statement is true.
